[Percutaneous renal puncture guide by a novel real-time needle-tracking ultrasound system for percutaneous nephrolithotomy: analysis of 16 cases].
2014
Objective: To evaluate the feasibility and efficacy of percutaneous renal puncture in percutaneous nephrolithotomy guided by novel needle-tracking ultrasound system. Methods: From may to october 2013,16 cases of percutaneous nephrolithotomy were performed under the guidance of ultrasound system. The clinical data including the time of completing percutaneous renal puncture,the color of urine sucked out from the kidney calices,and the complications were analyzed retrospectively. Results: Of the16 patients,18 percutaneous renal access were established guided by ultrasound system. All of them were successtul for the first time,and the average time of completing percutaneous renal punctures was( 26.90 ±11.37) s( 15 to 54 s). After the operation,the hemoglobin decreased by( 9.56 ±5.27) %( 1.41% to 24.06%),and no complications occurred except for postoperative fever in 2 case. Conclusion: The novel ultrasound system is a safe and effective technique that can reduce the technical difficulty of percutaneous renal puncture in percutaneous nephrolithotomy.
